SP of 18 books = CP of 21 books
Let the SP of 1 book = Re 1
SP of 18 books = Rs. 18 = CP of 21 books
So we get CP of 21 books = 18
SP of 21 books = Rs. 21
SP is greater hence profit
Profit = SP - CP = 21 - 18 = 3
Profit% = Profit/CP * 100
= 3/18 * 100
= 100/6
= 16.66% profit

Answer:
profit % = 16.666666%
Step-by-step explanation:
SP of 18 books = CP of 21 books
Let the SP of one book = Rs. 1
SP of 18 books = Rs. 18 = CP of 21 books
so we get CP of 21 books = Rs.18
SP of 21 books = Rs. 21
SP is greater hence, profit
Profit = S.P - C.P
= 21 - 18
= 3
profit % = profit / C.P *100
= 3 / 18*100
= 100/6
=16.66%
